Application filed February 28 1898- Serial No. 671,956. (No model.) I

To aZZ whom it may concern.-

Be it known that 1, JAN GRUBINsKI, asubject of the Czar of Russia, residing at Warsaw, in the Province of Warsaw and Kingdom of Poland, Russia, have invented certain new and useful Improvements in Apparatus for superheating Steam, (for which I have received patents in the following foreign countries: Germany, filed September 14, 1897, issued March 7, 1898, no number; France, filed February 7, 1898; Belgium, filed February 5, 1898, issued. February 15,1898, No. 133,578; Austria, filed February 5, 1898; Hungary, filed February5, 1898; Italy, filed March 12, 1898; England, filed February 14, 1898, sealed April 2,1898, no number; Switzerland, filed February 12,1898; Sweden, filed February 24, 1898 Norway, filed March 1, 1898; Denmark, filed February 25, 1898, and Russia, filed February 17, 1898;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in an apparatus for superheating steam, the object being to providea simple, durable, and efficient device of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my'invention, Figure 1 is a sectional view, partly in elevation, of a device for superheating steam constructed in accordance with my invention, taken on the line 1 1 of Fig. 2. Fig. 2 is a view in elevation of the center plate.

My device consists of a flat box or receptacle of circular form, composed of two dished heads a, adapted to be secured together by means of rivets or in any other suitable manner. The said box or receptacle is divided into two compartments by means of a platepass through the heads a, the sleeves cl, and the plate I). Mounted upon said plate I) at regular intervals and extending spirally over both faces of the same are a plurality of angle-irons f, which are adapted to abut with the outer edges of their outwardly extending flanges against the inner faces of the heads a, thus dividing said box or receptacle into a plurality of parallel spiral passages in, beginning at points about midway between the center and periphery of said plateb and ending at the periphery thereof. Said plate I) is of less diameter than the inner diameter of said box or receptacle, so as to leave a passage Zto receive the superheated steam. Steam is admitted to the middle portion of said box or receptacle and follows the passages 70 to the passage Z, from which it is drawn off in any suitable manner. As the inlet and outlet for steam can obviously be provided at any desirable point and in any suitable manner, I have not shown the same.

My device is adapted to be placed where it is exposed to intense heat, and the steam admitted thereto being obliged to pass through the channels 70 will obviously become superheated.

Owing to the fact that I employ a large quantity of metal and provide a large heatingsurface my device will become easily heated and its temperature will not vary to an appreciable degree.

I claim as my invention-- 1. A device for superheating steam, comprising a flat box or receptacle divided into a plurality of spiral passages leading from a central to a peripheral chamber,substantially as described.

2. A device for superheating steam, comprising a box or receptacle divided between its ends into two compartments by means of a plate, each of said compartments being subdivided into spiral passages leading from central chambers to a peripheral chamber, substantially as described.

' 3. A device for superheating steam, comprising a flat box or receptacle, consisting of two dished heads secured together at theirperipheries and divided into two compartments by means of a plate interposed between the same and having a diameter less than the interior diameter of said box or receptacle, and said compartments being subdivided into a plurality of spiral passages by means of angleirons secured to said plate and abutting with their outWardly-extendin g flanges against the inner faces of said heads, said passages extending from central chambers to a periph* eral chamber, substantially as described. IO

In testimony whereof I affix my signature in presence of two Witnesses.
